Tree Spraying

What is tree spraying?

Tree spraying is designed to protect your valuable landscape from destructive insects, seasonal fungal diseases, and environmental stress. As a state-licensed and fully insured pesticide applicator, we utilize targeted, eco-conscious application methods to safely treat common Montana threats—including bark beetles, aphids, spruce spider mites, scale insects, needle cast and much more. Rather than taking a blanket approach, we carefully time our treatments to align with local pest lifecycles, ensuring maximum protection for your trees, lawns, ornamental plants and more all while minimizing impacts on beneficial organisms and surrounding environments. Whether you need proactive spring defense against wood-boring insects, dormant oils to suppress overwintering pests, or curative foliage treatments, our expert spraying services keep your property’s trees healthy, resilient, and vibrant all season long

Common questions

Is tree spraying safe for my family, pets, and beneficial insects?

Safety is our top priority. As state-licensed applicators, we strictly follow EPA guidelines and use targeted treatments applied at specific times in a pest's lifecycle. We ask that children and pets remain indoors during the application and until the treatment has completely dried (typically 1–2 hours). Furthermore, our targeted approach minimizes impact on beneficial pollinators like bees and ladybugs.

Why should I hire a licensed professional instead of buying store-bought spray?

Commercial pesticide applicators have specialized training in pest identification, proper dosage calculation, safety protocols, and calibrated equipment. Store-bought sprays are often overused or applied at the wrong time in the insect's lifecycle, rendering them ineffective and potentially harming your trees or surrounding foliage. Licensing ensures treatments are effective, compliant with state laws, and safe for your ecosystem.

Can spraying save a tree that is already dying or infested?

It depends on the severity of the damage. Tree spraying is most effective as a preventative measure or when caught in the early stages of infestation or disease. If a tree has suffered extensive structural or vascular damage, spraying may not reverse the decline, and removal might be necessary. We always conduct a thorough diagnostic assessment before recommending treatment.
